try adjusting your idle needle ccw. it should slow down the engine at center servo settings. also, for your attenna wire wont do that, it will just make your truck range shorter. you can always go to the local hardware store, buy some wire, twist it together with the old one(make sure its metal on metal) and extend your anttena. for your wheels, check to make sure the wire is in the reciver box, and make sure there are no cuts in the wire connecting servo to reciever box.also adjust your linkage to a set position that will close the carb more. hope this helps.
